Chrysanthemum plant named ‘Annecy Dark Yellow’

ABSTRACT

A new and distinct cultivar of Chrysanthemum plant named ‘Annecy Dark Yellow’, characterized by its anemone type inflorescences with spooned yellow-colored ray and darker yellow-colored disc florets; strong and erect flowering stems; early flowering response; good postproduction longevity; and resistance to Chrysanthemum White Rust.

Botanical classification/cultivar designation: Chrysanthemum×morifolium cultivar Annecy Dark Yellow.

BACKGROUND OF THE INVENTION

The present invention relates to a new and distinct cultivar of Chrysanthemum plant, botanically known as Chrysanthemum×morifolium and referred to by the name ‘Annecy Dark Yellow’.

The new Chrysanthemum is a naturally occurring whole plant mutation of the Chrysanthemum cultivar Annecy Yellow, not patented. The new Chrysanthemum was discovered and selected by the Inventor on Apr. 9, 2001 within a population of plants of the cultivar Annecy Yellow in a controlled environment in 's Gravenzande, The Netherlands.

Asexual reproduction of the new Chrysanthemum by terminal cuttings in 's Gravenzande, The Netherlands since May 10, 2001, has shown that the unique features of this new Chrysanthemum are stable and reproduced true to type in successive generations.

BRIEF SUMMARY OF THE INVENTION

The cultivar Annecy Dark Yellow has not been observed under all possible environmental conditions. The phenotype may vary somewhat with variations in environment such as temperature, daylength and light intensity, without, however, any variance in genotype.

The following traits have been repeatedly observed and are determined to be the unique characteristics of ‘Annecy Dark Yellow’. These characteristics in combination distinguish ‘Annecy Dark Yellow’ as a new and distinct cultivar:

1. Anemone type inflorescences with spooned yellow-colored ray and darker yellow-colored disc florets; typically grown as a spray type.

2. Strong and erect flowering stems.

3. Early flowering response.

4. Good postproduction longevity.

5. Resistant to Chrysanthemum White Rust.

Plants of the new Chrysanthemum differ from plants of the parent, the cultivar Annecy Yellow, primarily in ray floret coloration as plants of the cultivar Annecy Yellow have lighter yellow-colored ray florets.

Plants of the new Chrysanthemum differ from plants of the cultivar Annecy Lemon, disclosed in a U.S. Plant patent application Ser. No. 10/654,395, primarily in ray and disc floret coloration.

Plants of the new Chrysanthemum can be compared to plants of the Chrysanthemum cultivar Yellow Bijoux, disclosed in U.S. Plant Pat. No. 8,329. In side-by-side comparisons conducted in 's Gravenzande, The Netherlands, plants of the new Chrysanthemum differed from plants of the cultivar Yellow Bijoux in the following characteristics:

1. Plants of the new Chrysanthemum were stronger growing than plants of the cultivar Yellow Bijoux.

2. Plants of the new Chrysanthemum flowered earlier than plants of the cultivar Yellow Bijoux.

3. Plants of the new Chrysanthemum were more freely flowering than plants of the cultivar Yellow Bijoux.

4. Plants of the new Chrysanthemum had larger inflorescences than plants of the cultivar Yellow Bijoux.

5. Plants of the new Chrysanthemum were resistant to Chrysanthemum White Rust whereas plants of the cultivar Yellow Bijoux were susceptible to Chrysanthemum White Rust.

Colors in the photographs may differ slightly from the color values cited in the detailed botanical description which accurately describe the actual colors of the new Chrysanthemum.

The photograph at the top of the sheet comprises a side perspective view of a typical flowering stem of ‘Annecy Dark Yellow’.

The photograph at the bottom of the sheet comprises a close-up view of typical leaves and inflorescences of ‘Annecy Dark Yellow’.

DETAILED BOTANICAL DESCRIPTION

In the following description, color references are made to The Royal Horticultural Society Colour Chart, 1995 Edition, except where general terms of ordinary dictionary significance are used. The aforementioned photographs and following observations and measurements describe plants grown during the spring in 's Gravenzande, The Netherlands, under commercial practice in a glass-covered greenhouse. Plants were initially given long day/short night treatments followed by short day/long night treatments to induce flower initiation and development. During the production of the plants, day temperatures were about 18° C. and night temperatures were about 17° C. Plants were about ten weeks from planting when the photographs and the description were taken.

Botanical classification: Chrysanthemum×morifolium cultivar Annecy Dark Yellow.

Commercial classification: Anemone type Chrysanthemum typically grown as a spray-type cut flower.

Parentage: Naturally occurring whole plant mutation of Chrysanthemum×morifolium cultivar Annecy Yellow, not patented.

Propagation:

Type.—Terminal tip cuttings.

Time to initiate roots, summer.—About 5 days at 20° C.

Time to initiate roots, winter.—About 6 days at 18° C.

Time to produce a rooted cutting, summer.—About 10 days at 20° C.

Time to produce a rooted cutting, winter.—About 14 days at 18° C.

Root description.—Fine and freely branching; white in color.

Plant description:

Petiole length: About 3 to 4 cm. Petiole diameter: About 2 to 3 mm. Color: Developing and fully expanded foliage, upper surface: 147A. Developing and fully expanded foliage, lower surface: 137C.

Inflorescence description:

Appearance.—Anemone type inflorescence form with spooned-shaped ray florets. Infloresences borne on terminals above foliage. Disk and ray florets develop acropetally on a capitulum. Not fragrant. Typically grown as a spray type, but can also be grown as a standard type.

Flowering response.—Under natural conditions, plant typically flower in November in the Northern Hemisphere. At other times of the year, inflorescence initiation and development can be induced under short day/long night conditions (at least 13.5 hours of darkness).
